Plasma troponin and creatinine levels after CA with and without VNS. A significant increase in plasma troponin levels was observed in both Control and VNS groups after CA as compared with their respective baseline levels (P < 0.001 and P < 0.01). However, the increase was less severe after VNS. A significant increase in plasma creatinine levels was observed in both Control and VNS groups after CA as compared with their respective baseline levels (P < 0.0001 and P < 0.05). The increase in creatine was less severe after tVNS and treatment with tVNS tended to show improvement in creatinine levels as compared with Control (P = 0.09). N = 8 each. RM two-way ANOVA with Šídák’s multiple comparisons test. tVNS = threshold adjusted vagus nerve stimulation
